To all whom it may concern:

Be it known that l, PAUL Parana, a. subject of the King of Hungary, and resident of Astoria, in the county of Queens and State of New York, have invented new and useful Improvements in Dirigible Propeller- Mountings, of which the following is a specification.

This invention relates to improvements in mounting over my former invention, U. S. Patent #1,179,554, and has as its principal object the provision of means whereby the vanes '01- blades of the propeller may be directed so that the thrust of the same may be at an angle with the axis of the driving shaft.

A second object is to provide such mountings in forms applicable to existing structures or new installations whereby the ves sel may be directed without the use of rudders or vanes, in either a horizontal or vertical course.

Another object is to provide means whereby the axis of the propeller may be manipulated at any desired angle from within the vessel and held in a rigid manner in its adjusted position by guides.

' These and other objects, which will become more fully manifest as the disclosure progresses, are attained by the novel construction and combination of parts hereafter described and shown in the accompanying drawings, forming a material part of this specification, and in which Figure 1 is a fragmental top plan view of the propeller mounting, the vanes being shown. in an angular position in broken lines.

Fig. 2 is a horizontal sectional view, taken on line 2-2 of Fig. 1.

, Fig. 3 is a. face plan view of the guard element in detail.

Fig. 4 is a fragmental sectional view, taken on line H of Fig. 3, and

Fig. 5 is a, transverse sectional view, taken on line 5-5 of Fig. 2.

.In the drawings, a rigid support is used as a mounting for the driving shaft 11, the latter having a collar 12 in front of the support, the shaft being engaged with a universal joint comprised of crossing elements 15 the latter element being pivotally mounted in a yoke having arms 17, connected at the front by 9. rl 'd cross bar 18 and containing the rectan ar hub 20 of the propeller blades 21 the ab being held in posit on by means of the bolt 9.3,pass1ng Specification of Letters Patent.

through the arms 17 of the yoke and held rigidly therein by means of the nuts 24 as is clearly apparent in Fig. 2.

Formed with the bar 18 is an extending hub 28 in which the shaft 29 is secured by means of a pin 30 or the like, whereby the shaft is caused to rotate. The extreme 'opposite end of the shaft is provided with a spherical element or ball 32, the same being seated in a slide 33 and held therein by means of the clamp nut 35 in a manner which prevents the ball from being withdrawn, but allows it to rotate freely within the hearing.

The slide 33 is suited to operate in guideways 40, and 42, arranged at right angles one to the other so that the slide may be moved either to the right or left, whereby the ropeller vanes are similarly moved or so tiat the direction of the vessel may be diverted from-a horizontal plane either up or down as may be desired, according to whether the slide 33 is above or below the axis of the driving shaft 11.

Inorder that the slide 33 may be moved freely within the arcuate slot ways and 42, the same are formed within a concave support 45, the center of which is rigidly mounted in register with the axis of the driving shaft 11, the radius of the slots 40 and 42 being coincident with the distance between the center of the universal joint of the propeller mounting.

Means for diverting the slide 33 may be applied to the extending ends of the universal joint elements 15 and 16 or otherwise as may be preferred in a manner which will be obvious to those skilled in the art.

Thus it will be seen that a propeller mounting has been disclosed which is capable of being directed in any preferred course so that a vessel, particularly of the airshi type, may be guided and controlled as wel propelled and without the use of extraneous appliances, as ru.dders,'vanes or the like.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a. dirigible propeller mounting, the combination with the propeller blades, a yoke therefor, and means for rotating said blades, of a universal joint interposed between said oke and said driving means, a shaft exten ing from the said yoke oppositely from said. driving mcans, a slide engaged with said undo guide for said L" in I diilgiiiiv prupi-ili-r limliuling, Uh, ind'iimlmi Uh tin prupullvn a support at Iii; 'nl i Liwrvul. a: driving simii "for said l[pn"i- .l uniwlwal juinl imhiiwn said diii' mg in and mid support nu m'm i-xu-ndir m w mil mm Nlid mppm'i normally i i '15 p amu. 01' wild driving shaft, in am? i'ui'iiiud m1 mid :mm :1 slidv s Q, ;i. quid Hlliivl'll'ili end, and arm at, mid hiliil, tliu radii of Willi-h an yd liiili it) liwir distance from the cum vrmdiimdiun with a pmpvHi-x'. a d1'i\ ing d ii i'i timrui'or, a rigid supjmi'i i'nr :Luid driving shaft. a yoke remaining the huh of wilii 1m, pellel', universal] joint connuctimm iJUiWUVH said yoke-and said driving shaft, an arm i-xivuding nutwnrd from said yoke pin-pundicu] 1r in the blades of said propeller, ufcli an guides rigidly nmuntvd UllJUHilP 10 said yoke. and menus formed ml said :u'm 0pmablc within mid urcluite gllidis ir. iii-ruby Hm ungularity of the pl'upuiim' hlzidw may be controlled.
